jqueryui插件里有现成的效果，叫selectmenu，代码如下（示例代码里有三种不同的方式供选择）：
<!DOCTYPE html><html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="lib/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="lib/jquery-migrate-1.2.1.min.js"></script>
<link rel="stylesheet" href="lib/jquery-ui.min.css?v1.11.0-beta.2" />
<script src="lib/jquery-ui.min.js?v1.11.0-beta.2" type="text/javascript"></script>
<title>自定义下拉表单</title>
<style type="text/css">
fieldset {
border: 0;
}
label {
display: block;
margin: 30px 0 0 0;
}
select {
width: 200px;
}
.overflow {
height: 200px;
}
</style>
<script>
$(function() {
$( "#speed" ).selectmenu();
$( "#files" ).selectmenu();
$( "#number" )
.selectmenu()
.selectmenu( "menuWidget" )
.addClass( "overflow" );
});
</script>

追答用div的目的不也就是要改变样式吗？这个插件就是根据select然后自动添加div代码，可以修改css样式的，你用firebug看一下就知道了，这么写后台也好获取数据，单纯用div，还要写js代码，把数据单独提取出来，不麻烦吗?
